PATENT BIRNEY C. BATOHELLER, OF PHILADELPHIA, PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 623,972, dated May 2, 1899.

Application filed March 26, 1898.

To all whom it flea/y concern:

Be it known that LBIRNEY O. BATCHELLER, a citizen of the United States of America, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Carriers for Pneumatic-Despatch Apparatus, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to the tubular shells used as carriers in pneumatic-despatch apparatus, and particularly to the means whereby the caps or lids of the shells are locked in position, the object of my invention being to provide, in addition to looks or bolts for fastening the cap to the shell and means for operating such bolts, means for preventing the motion of the locking-bolts in a direction to effect the looking at any other time than when the cap is in proper position to be locked to the shell. Y

In my former patent, No. 54:0,133, of May 28, 1895, I have shown and described a device for locking the caps to the shells in which provision is made against the insertion of the carrier in the despatch-tube until after the locking-bolts have been shot. This mechanism is excellent as far as it goes; but it does not exclude the possibility of shooting the bolts before the lid or cap is closed down, and my preferred form of apparatus involves the device of my former invention, together. with the additional locking devices for preventing the shooting of the bolts when the cap and shell are not in proper relative position.

Reference being now had to the drawings, in which my invention is illustrated, Figure 1 is a longitudinal section through the cap end of a carrier, taken as on the section-line 2 2 of Fig. 2. Fig. 2 is a cross-sectional view, taken as on the irregular section-line l 1 of Fig. 1, looking toward the cap. Fig. 3 is a fragmentary sectional view taken as on the line 3 3 of Fig. 2. Fig. 4c is a plan view of a simple form of locking-cam which I have found serviceable. Figs. 5 and 6 are-plan views of two of the three eccentrics and co acting yokes, the third being shown in full lines in Fig. 2.

Serial No. 675,268. mamas.)

A indicates the shell of the carrier; 13, a supporting-ring; (J, ablock secured to one side of the open end of the shell for the attachment of a hinge E.

D D D are bolt-holes formed through the shell.

F is the cap of the carrier, hinged to it, as shown, by the hinge E and formed with a flange F, which in the plan shown extends over the open edge of the shell.

F is a circular opening formed through the cap at some distance from the center thereof and from the center of the shell.

G, G, and G are bolts moving in guidelugs g g, &c., secured on the inside of the cap and in position to enter the bolt-holes D when the lid is closed firmly down on the shell. Each of the bolts is secured to a plate, such as H, II, and H in which is formed an ecare also preferably provided with rear extensions, as indicated at H H 850., which move through guide-lugs g, secured on the inside of the cap.

I is a circular flanged washer fitting in the opening F and having a squared perforation through which extends the squared shankbolt J upon which and between the head of the bolt and the outer face of the cap is secured the lever-arm P. Also secured upon the squared bolt J and lying inside of the flanged washer I is the locking-cam K, having, preferably, as shown, the locking-shoulders k It. (See Fig. 4.) Lying inside of the cam K is the eccentric L, around which passes the yoke h of the bolt G. Then after the interposition of a washer I comes the eccentric L, around which passes the yoke h of the bolt G. Then comes another washer 1 then the third eccentric L around which passes the yoke h of the bolt G Then, as shown, washers I and I are secured on the squared portion of the bolt, inside of which lie the washers I", surrounding the rounded and threaded end of the bolt, and then the nuts J and J It will be observed that the lever P being pivoted eccentrically or away from the center of the cap and being of a length which will only permit it to lie within the circumference of the cap when the bolts are shot,

centric-yoke, such as h h 72/ and which plates to be shot.

this construction prevents effectually the unlocking of the cap in transit and when inclosed in a tube.

To the exten t above described,as illustrated in the drawings, the invention does not differ in any substantial degree from that shown in my former patent above mentioned, with the' single exception of the presence of the locking-cam K, and as in my former patented construction the bolts are operated by moving the lever P and by its means turning the shaft J and the eccentrics secured thereto, which in turn operate to simultaneouslyshoot or withdraw the bolts. In my present construction, however, I provide, in addition to the parts already described, a locking device which prevents the motion of the lever P to a position to lock the bolts, and consequently prevents the locking of the bolts at all times, except when the cap is in its proper position on the shell, at which time only the said looking device is withdrawn, permitting the bolts As shown, I pivot on a supporting-lug M and to a pin N secured to the said lug a lever N N, the end N of which in normal position, in which it is held by the action of a spring 0, passes between the lockingshoulders 70 7c of the cam K when the bolts are open and prevents the said cam from turning to a position corresponding to a shot position of the bolts as long as it remains in the said normal position. The other end N of the pivot-locking lever I arrange to go opposite to the edge of the shell A, as shown in Fig. 3, and so that when the cap is shut down on the end of the shell the shell will engage and push the end N of the lever to the position shown in dotted lines in Fig. 3, the result of which is to raise the locking end N to the position shown in dotted lines, where it clears the locking-cam K and permits the lever P and the bolts to be thrown into the position to look the cap to the shell.

Of course the special construction shown in the drawings may be varied in very many wayswithout modification of the essential features of my invention, and it must be understood that I do not limit my claims to this special mechanism, which is given simply as the best form in which I have heretofore embodied my invention.

l'Iaving now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a carrier-shell, a cap for closing the open end thereof, bolts for securing the cap to the shell and means, as lever I, for operating saidbolts, of a look, as N, arranged to normally prevent the motion of the bolts to lock the cap, and means as described whereby the placing of the cap in proper position on the shell withdraws the lock and permits the bolts to operate.

2. The combination with a carrier-shell, a cap for closing the open end thereof, bolts for securing the cap to the shell and a bolt-opcrating lever as 1 pivoted away from the center of the cap and arranged to lie partly outside of the periphery of the cap at all times except when the bolts are shot, of a look as N arranged to engage and hold the lever P in position corresponding to the open position of the bolts, and means as described whereby the placing of the cap in proper position on the shell withdraws the lock and permits the lever P to operate.
